2.4 Design and mode of operationThe device is based on a piezo-resistive sensor element that is suitable formeasuring overpressure, under-pressure and differential pressure. The pres-sures to be compared directly act on a silicon diaphragm equipped with a meas-uring bridge.When the pressure is equal, the measuring diaphragm is is in its idle state. If apressure difference occurs, the diaphragm is deflected, causing a change inresistance of the applied measuring bridge. This change is evaluated by theelectronics integrated in the instrument and converted into a display, switchingcontacts and output signal.The output signal can be damped, spread, inverted and also non-linearly trans-formed via a table function.In the version with only one channel, the device has one analog output and twoswitching outputs. In the version with two channels, the device has two analogoutputs and four switching outputs. Analog and switching outputs can be freelyassigned to the measuring channels.The device can be equipped with two digital interfaces.1. USB OTG

All devices have a USB interface which can be used for firmware updatesas well as for importing and exporting parameters. This can be done with aUSB stick or by connecting a computer (e.g. laptop).

2. RS485 Modbus RTUThe device can optionally be equipped with a Modbus interface. In thiscase, the analog and switching outputs are not available. The measuredvalues can then be interrogated by the master via Modbus.

At the factory, the device is calibrated for vertical installation, but the installationposition is arbitrary. For any installation positions that are not vertical, the zero-point signal can be corrected via the installed offset correction.The enclosure protection type IP 65 is only guaranteed, if a suitable power sup-ply cable is used (see accessories).

3.2 Mounting in explosive areas• If operated in explosive areas, the valid local regulations and guidelines for

the installation and operation of electrical systems in explosive areas mustbe observed.

• If units are used in potentially explosive areas, the personnel must receiveadditional training or briefings or have a permit to work on explosion-protec-ted units in potentially explosive systems.

DANGER! The operator must ensure that any falling objects cannot collidewith the installed unit.Steps must be taken to prevent the impact creating sparks so that the protectionclass of the casing is no longer guaranteed. This can be avoided by attachingprotective cover, a protective housing or similar.

3.3 Process connection• By authorized and qualified specialized personnel only.• The pipes need to be depressurized when the instrument is being connec-

ted.• Appropriate steps must be taken to protect the device from pressure surges.• Check that the device is suitable for the medium being measured.• Maximum pressures must be observed (cf. Tech. data)

The pressure lines must be kept as short as possible and installed without anytight bends to avoid delays.The pressure lines must be installed at an inclination so that no water pocketsare created. If the required gradient is not reached, water filters need to be in-stalled at suitable points.The process connections are marked with (+) and (-) symbols on the device.The pressure lines must be mounted according to these symbols.

The connectedslaves only react to direct commands from the master, which is why communic-ation between the slaves is not possible.To guarantee fault-free data transmission, we recommend terminating the endpoint of the Modbus RTU network with a 120 Ω resistor. This bus terminationresistance is available as an accessory.

3.4.3.1 Connection to an existing Modbus RTU networkIt can be connected to an existing Modbus network via a conventional T-piece(passive TAP).

Fans are usually equipped with an inlet cone. The volume flow measurementconsists of one or more measuring points in the inlet cone and one measuringpoint in the suction chamber of the ventilation unit. The differential pressurebetween the measuring points is used to calculate the volume flow.The basic formula given applies to a frictionless and loss-free flow with constantdensity. In reality, therefore, a correction value caused by the design and otherfactors must be taken into account.The fan manufacturers have determined the correction value for each inletnozzle.

For example: Channel 1: Basic measuring range: 0 … 100 PaThe measuring range is defined as 10 … 90 Pa. The green range should be 0… 60 Pa. Then the critical range (yellow) up to 70 Pa starts. This is where thered range that ranges up to the measuring range end at 90 Pa starts. The lowercolour changes red-yellow and yellow-green are switched off.

The lower colour changes S1 and S2 are 'switched off' by placing thresholdsoutside the measuring range. If the threshold values were to be laid precisely atthe start of the measuring range, the display would shine red in the zero-point,

Red > Yellow > Green The cause for this lies in the priority of the colours. The red colour has priorityover the yellow colour and this has priority over the green colour.

The air filter in this example has the task of retaining dust impurities from theoutside air. With increasing contamination, the pressure difference measuredabove the filter increases. As soon as the pressure difference exceeds the setlimit value, the filter monitoring system signals the contamination of the filter.This is indicated as a fault.The volume flow control keeps the air volume flow constant despite increasingcontamination by increasing the fan speed. However, the pressure drop acrossthe air filter does not only depend on the degree of contamination, but also onthe size of the volume flow.The pressure drop changes as a square of the volume flow. Therefore a reduc-tion of the volume flow from 100 % to 50 % means a reduction of the pressuredrop across the filter element from 100 % to 25 %.

Fig. 104: General filter characteristic curve


74 BA_EN_DE90

In order to be able to determine the degree of contamination by means of differ-ential pressure measurement, it is therefore necessary to carry out the meas-urement at maximum volume flow. This measurement is carried out at regularintervals.This is not necessary for dynamic filter monitoring. An approximation of the filtercharacteristic curve is calculated by determining some system-specific paramet-ers. With this approximated characteristic curve, the degree of contamination ofthe filter can now be determined at any time without changing the fan speed.

ParameterisationNOTICE! The filter characteristic curves shown serve to illustrate the rela-tionships and can only be transferred to a real characteristic curve to alimited extent.The pressure difference in the filter increases due to the storage of dust. Ap-proximately, this increase is quadratic for large dust filters and linear for particu-late air filters. The approximation formula to be used therefore depends on theplant. This is determined by the parameter Approximation . Experienceshows, however, that the linear approximation is sufficient in most cases.The two input channels are assigned with the parameters Channel ∆p (dif-ferential pressure measurement) and Channel Q (volume flow measure-ment). Please make sure that you do not assign the same channel twice andthat the input channels have been parameterized according to the measure-ment task (see Measurement C1 [ 47]).In general, the filter characteristic curve looks as follows:

The measurement errors resulting from the characteristic curve shift are muchsmaller than shown in the graph, since the curvature of the real characteristiccurve is significantly smaller. This superelevation was chosen for reasons ofpresentation.With the parameters Displ.range C3 start and Displ.range C3end the display characteristic curve can be spread appropriately. Since thelimit curve for the contaminated filter is now fixed, the degree of contaminationof the filter can be determined dynamically for any operating point.

Square-root approximation of the characteristic curveIf the filter characteristic curve is strongly curved, a more exact approximationmay be necessary. In this case, the Approximation parameter can be setto the ‘Square-root' value.The software then calculates a square root characteristic from the other para-meters.

The 'triggering' channel is marked witha dot. When re-entering the green area, the indicators are deleted.

Example Two channels are displayed on the power indicator. First, channel 2 triggers agreen-red color change. A short time later, the same colour change is triggeredby channel 1.
